Patented Jan. 17, 1939 PATENT OFFICE HUMIDIFIE-R James W. Galloway, Cedar Falls, Iowa, assignor to The Automatic Humidifier Company, Cedar Falls, Iowa Application May 3, 1937, Serial No. 140,405

2 Claims.

My invention relates to improvements in furnace humidifier installations, and an object of my improvements is to furnish different means for removably and separately mounting a humidifier pan and accompanying trough and thermostat within the hot air jacket of a furnace.

Another object of my improvements is to combine with the furnace and its apertured jacket, a hand-hole plate adapted to be secured over the jacket aperture, and a gate member slidably and removably mounted upon the hand-hole plate, operable when the gate is in opened position to be manually lifted and supported in its lifted condition to permit the humidifier pan and also the thermostat and trough accompanying it to be inserted into or removed from the jacket when necessary.

Another object of my improvements is to provide the hand-hole plate with an aperture to removably receive an end projection of the humidifier pan to support the pan within and across the jacket in a suitable position.

I have accomplished these objects by the means which are hereinafter described, claimed and i1- lustrated in the appended drawing.

It is to be understood, that various specific changes in the forms and connections of said devices may be made without departing from this invention or the scope of the claims.

Fig. 1 is a front elevation of the upper end of a hot air furnace having parts of the front and side walls broken away to show the mounting of a humidifier and associated thermostat therein. Fig. 2 is an enlarged elevation of the hand-hole plate with the gate member mounted movably thereon.

I is the upper part of a hot air furnace above I2 is an open top pan horizontally supported across the interior of the jacket above the crown 26. I3 is an overflow pipe traversing the jacket with its inner end loosely slidably seated in the casing I, to maintain it level horizontally, and I4 is a wedge-shaped bracket, projecting horizontally outwardly from the opposite end of the pan, with down bent termination I6 in the pan and secured thereto by bolts I5 connecting it to the flange I2.

The furnace jacket I has an aperture of sumcient size and proper shape, and, referring to Fig. 2, a substantially rectangular plate 2 is mounted about and over this aperture eXteriorly of the jacket and secured removably by screws or other fastening means traversing the holes 3. The plate 2 has a depending part 8 having a medial horizontal slot 9 registering with a similar slot in the jacket I. The bracket I4 on the pan I2 extends outwardly through said slot wedgingly, securing the pan removably upon and inside the jacket.

The plate 2 has a relatively large substantially rectangular opening 5 including a notch I0 below. At opposite sides the plate 2 has horizontally alined fixed pins 4 to traverse vertically disposed slots I in the opposite end parts of a gate or slide plate II positioned to move vertically upon the outer face of the plate 2 and covering the aperture 5 thereof when the plate II is in a lowered position. These pins 4 are headed at B with a wider diameter than the width of the slots I. At upper and lower circular ends the slots I are wider than the heads of the pins 4. The plate I I is shown in its lowered position with the upper wider ends of the slots traversed by the pins 4, and the plate I I then closes the aperture 5 of the plate 2. The plate II may be manually lifted to a position where the heads 6 of the pins 4 may be in the lower wider ends of the slots I, and as the pin heads are of less diameter than the said wider ends, the plate II may be disengaged from the pins. Then the trough I8 with thermostat I'i mounted therein may beremoved outwardly by lifting them and then passing them outwardly through the aperture or hand-hole 5. Also, the pan I2 may be pushed rearwardly slidingly upon the loosely connected pipe I3, until cleared from the slots at 9 in the jacket I and plate extension 8, and the pan then removed by way of the aperture 5. The thermostat I1 is not claimed specifically herein, but may have as operating parts a bolt 20 to clamp the device to the jacket on the inside, an element of the thermostat having outside valvular and other elements such as supply pipe II, a valve chamber 22, spring 23 variably tensioned by a nut 24, and a pressure plate 2I. The thermostat is secured in and above the trough I8 by screws I9.

I claim:

1. In a hot air furnace, a jacketed hot air dis,- tributing chamber having a relatively large side wall aperture, a plate having a relatively small aperture in its lower part and a larger aperture thereabove and the plate being secured across said wall aperture, a second plate vertically slidable upon and removably mounted across the first plate and its larger aperture, an open pan in said chamber having an inwardly removable wedgeshaped bracket member seated in said small aperture, and a water delivery trough and thermostat traversing the larger aperture in the first plate.

2. In a hot air furnace, a jacketed hot air distributing chamber having a wall aperture, an apertured plate with lower edge part notched and secured removably across said wall aperture,

a supply trough traversing" the notch of said apertured plate, a slidable closure plate movably mounted across all but the notch of the aperture of the first plate, an open top evaporating pan positioned within and across said 10 chamber and having an end bracket fixed there- JAMES W. GALLOWAY.
